WINDOWADJUSTER AND Loox.

` Application filed september 25, 1923. seriai No. 664,703.

To @ZZ whom 'it 17mg/ concern."

Be it known that I. Mans M. Lansnm a citizen of the United States, residing 'at Colt-on, in the county ot San Bernardino and State of California, have invented new and useful Improvements in Window Adjusters and Locks, ot whichA the tollmving is a specication. y

This invention relates to-iniprovemonts in window adjusters. i f

An object is to provide Van improved means for opening and closing aiwindow. Another' object is to provide a means which' will -hold a Window in any desired position. A further object is to provide a window ad'- justerwhich will lock a window; in closed position, the locking parts being remotely situated from the sash. f

The-foregoing and other objects willV be made manifest in the following spec-ilica-v tion oit an embodiment ot this invention?r i illustrated by the accompanyingfdrawings,

in which: Y

Flgure 1 1s ahorizontalV section juster is mounted. j g Y Fig. 2 is an elevation. of awindow frame,

parts being broken'away and the sash being shown in open'position. Fig. 3 is a partial outside elevation of a windowV frame showing the application of f and suitably housed within a casing C hereinafter more fully described. Adjacent the lower end of the shank 14 and securely mounted thereon as by a keylG is a pinion 17 engaging the gear 18 having a spindle 19 mounted within the aforementioned casing. A rack 2O which is slidable within the casing C engages the gear 18. The rack 2O is provided with an arm 21 extending through a slot 22 in the window frame 23, the arm 21 being threaded to receive a handle 24 through a window frame-infwhlch the wmdow adof the window frame. I Y

It will be seen that when the handle 24 side to side, producing` rotation oflvthe gear P ATENT] which may be screwed'dowtn',` as shoivnf'by l dotted lines in Figure 1, lupon a Vslotted plate 25 mounted upon the v.insidetace 2G -is freed from contact withy the plate 25, the y arm 21 andthe rack 20 may be moved 'frein 18Y and the pinion -17 together vwith the f shank 14, which causes swinging movement 'of the window sash 10 upon a lvertical anisyl `in this case.

sii-ed position it may be 'friet-ionallylocked* n `handle. '245 VVhen'the sashjis inthe 'de-A in place by screwing down the tightly against the plate 25.`

The casing C enclosing the operating"I mechanism preferably consists; oif three pieces, including a member 27 having aslot 28 through which extends the arm 21 and also a groove 28a in which slides thelrack 2O."v The p1eces29and0 haveflanges 29 and 3021 respectively for fastening to the 76 Imember 27. Theseppieces'arejoined as `at 315 and have recesses to"receive the ends ofh Vthe spindle 19 andarecomplementary; with the exception that the piece 29has la" tubular v portion 32 which houses the shank "14. Itisy seen that thecasing enclosesfthe entire operating mechanism,f keeping'it free fromA dirt and foreign matter.

Then fastening thesash "1'0" t tothe Win-f dow frame 1t is necessary -ithat the upperv pointof attachment be directlyabove' the?,r shank 14 when the-sash isfto be "swung-'about n a vertical axis asshovv'n; 5vTo this'endl the plate 33, having peiiorations 34 for mountfy ingupon the top edge ofthe sash 10, is pro` vided, having a 'pin 35' which is placed di;l

rectly above the shank 14 and 'received-by a" bushing 36 which is recessed in the window frame and attached thereto by nails or screws passing through apertures 37 yin the plate 38.

The threaded shank and the handle piece 24 provide for the ready adaptation of the device to window frame structures of ditn ferent dimensions.

It is seen that a combination window adjusting device is provided which will hold the sash at any desired opening and which will lock the window when closed, the locking parts being inaccessible from the outsic e.

Further embodiments, modifications and variations may be resorted to within. the principle of the invention.

What is claimed is:

l. A window adjuster and lock comprising means adaptedto be mounted within a window casing and having a member forming a pivot for the sash to be adjusted and operative to swing the sash, a handle disposed for access at the window casing, and means connecting the handle and said member whereby the latter is adapted yto be rotated to swing the sash, said handle forming a friction locking device for securing the sash in its several positions.

2. A window adjuster and lock comprising means adapted to be mounted within a window casing and having a member torming a pivot for the sash to be adjusted and operative to swing the sash, a handle disposed for access at the window casing, and means connecting the handle and said member whereby the latter is adapted to be rotated to swing the sash, said handle being adapted for reciprocating movement parallel to the face of the window casing and adapted to form a friction locking device for securing the sash in its seve-ral positions.

v3. A concealab-le window adjuster and locking device including Aa rotative member connectible to Va sashtor be swung from one position to another on the axis of said member, a mounting part -in which said member is journaled, geary means carried by said mounting part, a rack engaging said gear means, and a handle adapted to be disposed in an accessible position and whereby the rack and said gear means are operated to swing the sash, said handle including a threaded shank and a handle piece adjustably mounted onA the shank.

4. A concealable window adjuster and locking device including a rotative member connectible to a sash to be swung from one position to another on the axis of said; member, a mounting part in which said member is j'ournaled,l gear means carriecflA by said mounting parti, a rack engaging said gear means, and a handle adapted to be disposed in an accessible position and whereby' the rack and. said gear means are operated to swing the sash, said handle including a threaded shank and a handle piece adj ustably mounted on the shank and whereby the adjuster parts may be locked .in various positions. Y

5. A window adjuster and lock, comprising a mounting member adapted to be enclosed within the window casing, a pivot forming member for a sash, ournaled within said mounting member whereby the sash may be turned on the axis of said pivot, a pinion carried by said pivot forming member, a gear engaging said pinion, a rack adapted to engage said gear and produce movementl ot said sash, and means for frictionally looking said rack in any position.

6. .A window adjuster and lock comprising a pivot forming member, upon which a sash is adapted to be pivoted, means whereby said sash may be rotated by said pivot 'forming member, a pinion upon said pivot forming member, a gear meshing with said pinion, and means for rotating said gear so as to rotate said pinion and pivotforming member and thereby swing said sash.

7. A window adjuster and lock comprising a pivot forming member, upon which a sash is adapted to be pivoted, means whereby said sash may be rotated by said pivot forming member, a pinion upon said pivot forming member, a gear meshing with said pinion, and a rack meshing with said gear adapted to rotate it upon sliding movement whereby said pinion and pivot forming member may be sash. l

8. A window adjuster and lock comprising a pivot forming member, upon which a sash is adapted to be p-ivoted, means whereby said sash may be rotated by said pivot forming member, a pinion upon said. pivot forming member, a gear meshing with said pinion, a rack meshing with said gear adapted to rotate it upon sliding movement whereby said pinion and. pivot forming member may be rotated. soE as to swing the sash, and means for locking said rack any desired position.
